Smartphone: no reception with o2

• Airplane mode: Turn Airplane mode on and off. While this is simple, it can sometimes work small miracles.
• Restart: If your smartphone is to blame for the network problem, it is usually solved by a restart. Simply switch the phone off and on again.
• SIM card: Remove the SIM card and clean the contacts. A microfiber cloth is best, but a slightly damp finger can do it too.
